我们给出了对总质量范围为100-450M圆点、分量质量比在1：4：1之间的非自转中等质量黑洞合并产生的引力波的弱模式爆发搜索结果。搜索是根据LIGO和Virgo探测器在2005年11月至2007年10月期间收集的数据进行的。搜索没有观察到可信的信号，它限制了中等质量黑洞合并的天体物理速率作为成分质量的函数。在以88+88M圆点为中心的最有效检测面元中，对于非自旋源，在90%的置信度水平下，率密度上限为每MPC(3)0.13。
We present the results of a weakly modeled burst search for gravitational waves from mergers of nonspinning intermediate mass black holes in the total mass range 100-450 M-circle dot and with the component mass ratios between 1: and 4:1. The search was conducted on data collected by the LIGO and Virgo detectors between November of 2005 and October of 2007. No plausible signals were observed by the search which constrains the astrophysical rates of the intermediate mass black holes mergers as a function of the component masses. In the most efficiently detected bin centered on 88 + 88 M-circle dot, for nonspinning sources, the rate density upper limit is 0.13 per Mpc(3) per Myr at the 90% confidence level.
